And fans have been told to congregate at a specially created fan zone in the city so they can get a police escort to the stadium, as local authorities try to stop a repeat of the trouble seen at Goodison Park.

One supporter has already revealed Split fans had cornered him and forced him to remove his Everton polo shirt.

He told the Liverpool Echo: "I was just walking in the street when suddenly there were four big blokes all around me.

“One of them said, “give us your T-shirt,”, and then leaned in further to me, and growled more threateningly, “Give us your T-shirt.

“ I was standing there with nothing on my torso. I had to go and buy something.

“It was pretty intimidating, and it shook me up.”

Some supporters have expressed their fears violence will erupt before the second leg match tonight.

Writing on fan forum, ToffeeWeb, one supporter wrote: "Strongly recommend zero fans travel to the second leg. It will be a bloodbath!"
